Given: ∠trs = ∠urs ∠tsr = ∠usr based on the given information and the algebraic and geometric properties presented or proven thus far, choose the congruence theorem that could be used to prove the triangles congruent. if it is not possible to prove the triangles are congruent, choose "not possible". sss sas asa not possible

ASA  is a possible  congruent theorem that could be used to prove the triangles congruent.

Step-by-step explanation:

Given

Proof: In triangle STR and SUR

1.Statement:

Reason: Given

2.Statement:

Reason: Given

3.Statement: RS=RS

Reason: Reflexive property of equality.

4.Statement:

Reason: ASA ( Angle-Side-Angle) property of congruence.

Hence, the triangle are congruent by the ASA congruence theorem .
